The table tennis wave hardness tester is suitable for testing the Vickers hardness of various table tennis balls. This machine is also known as a Rockwell hardness tester, table tennis ball Rockwell hardness tester, table tennis ball hardness tester, wave hardness tester, and wave hardness tester

Table tennis is a sport that combines skill and speed. Players need to have accurate control over the quality of the ball, and hardness is one of the key indicators. The table tennis hardness tester can objectively test the hardness characteristics of the ball, allowing players to better grasp the hardness of the ball; Balls with different hardness have different characteristics, some are more suitable for quick attacks, while others are more suitable for stable power. So as to choose the ball that suits oneself and improve the level of the game.

The table tennis ball hardness tester meets the standard:

Meet the requirements of relevant items in the GB/T 20045-2005 standard

Measurement principle of table tennis ball hardness tester:

During the test, place the table tennis ball on the testing platform, apply a fixed 50N load, automatically read the hardness A within 15 seconds, and return the indenter to its original position; Rotate the ball smoothly 180 °, test the hardness B using the same method, then rotate it 90 degrees to test the hardness C at the joint, and then calculate the hardness difference between the two readings of hardness A and hardness B

Functional characteristics of table tennis wave hardness tester:

1. The touch screen display displays real-time force values, displacement deformations, and automatically saves data; The display interface can display the test curve in real time; Test real-time parameters such as speed and deformation.

2. Using a high-precision, fully digital speed control system and precision reducer, the precision screw pair is driven for testing, achieving a wide range of adjustment of the test speed and smooth operation.

3. Adopting high-precision sensors and professional measurement and control software, with high testing accuracy, wide testing range, and simple operation.

4. Equipped with a standard micro printer, it can print results at any time and collect multiple test results

5. At the end of the experimental process, provide the measurement results of the hardness value. The process is time-saving and labor-saving, reducing the interference of subjective factors and effectively improving the reliability of testing.
